Wet process routes to phosphoric acid have bypassed phosphorus and taken over most of the rapidly growing fertilizer markets. Moreover, pollution problems are threatening existing large volume outlets for elemental phosphorus.

The Furnace Acid Process - JDC Phosphate

The Furnace Acid Process (FAP) uses carbon to reduce phosphorous to elemental phosphorous (P 2); the carbon oxidizes to carbon monoxide (CO) and calcium silicate (CaSiO 2) is formed. The elemental phosphorus is subsequently oxidized, to phosphorus gas and is then absorbed in water to produce phosphoric acid (H 3 PO 4 ).

Phosphoric Acid - Essential Chemical Industry

Phosphorus is an essential plant nutrient and is taken up by plant roots, usually as the dihydrogenphosphate ion, H 2 PO 4-, derived from phosphoric acid, H 3 PO 4.The manufacture of fertilizers that are used to rectify phosphorus deficiencies in soils depends on the availability of supplies of phosphoric acid.
